THE FED FILES -
Welcome to The Fed Files blog! This blog was originally in support of the Fed Files column in Monitoring Times magazine. Although the Fed Files, as well as Monitoring Times, will end with the December 2013 issue, this blog will continue to support the new federal monitoring column in The Spectrum Monitor magazine. If you would like to make a comment, pass along a tip or frequency you can send it to my email address, chrisparris @ thefedfiles.com

For a while I have been seeking information on the Los Angeles Metropolitan Detention Center, operated by the US Bureau of Prisons. I just stumbled on several P-25 voice channels and a Motorola trunked control channel that I think may be located at the LA MDC in downtown Los Angeles.

I think I have picked up this control channel on my last visit to LA, but the frequency is also used by the Camp Pendelton UHF trunked system, and I may have ignored it.

Still working on more system information but here is what I have so far:

Congratulations to David Stearns of Overland Park, Kansas. He won the drawing for an original copy of Monitoring Times, volume 1, #4. That issue of MT featured a front page story about the NTIA classifying the federal frequency Master File.

Thanks to everyone who entered the Fed Files drawing. We'll do it again when we come up with another prize!

After my recent trip to Arizona, I decided to dust off my listings for the DHS Customs & Border Protection Border Patrol. The Border Patrol continues to use its legacy VHF frequencies that are in blocks assigned to the Justice Department.

Currently the CBP Border Patrol doesn’t have a national channel plan like some agencies, but assigns their frequencies as needed locally. Along both the northern and southern border areas (except for southern California), the 163 MHz frequencies are the “backbone” repeaters with multiple input frequencies, from the 162 MHz, 165 MHz and 168 MHz blocks of frequencies. These frequencies can be used as repeaters or “local” simplex frequencies as well.

In areas not near the US borders, the former US Immigration agents, now part of DHS as the Immigration and Customs Enforcement may use frequencies from these blocks for local use.

Just finishing up a weeks work in the Phoenix, Arizona area and found quite a bit of federal activity. Despite the use of encrypted P-25 in southern California Border Patrol activity, southern Arizona remains a mix of analog and DES encryption.

The trunked sites listed are part of the Phoenix Metro P-25 800 MHz Public Safety system. They've been on the air for a couple of years now, but I don't know if anyone has actually heard them used yet.

As I have been reporting both on the Fed Files blog and in the Fed Files column in Monitoring Times, the Justice Integrated Wireless Network or IWN continues to grow and progress towards it's goal of being a nationwide digital trunked system for federal agencies. However, a recent audit of the systems shows there are some troubles for the IWN Project:

The above link contains some interesting information about the project and its use by various agencies so far.

The IWN expanded it's coverage from Washington State down in to Oregon and the Portland metro area in late 2006. It now appears to be in full use by Portland area federal agencies. We've been monitoring a LOT of activity on the system in the last month or so, almost 24/7. Several talk-groups on the system are showing the majority of the activity, but since the radios have been set up with the encryption selected automaticaly, I haven't heard any clear transmissions since the radio techs finished with their installation tests. But remember - systems are not encrypted, talk groups are not encrypted, but it is the individual radios that are encrypted.

So where will the IWN show up next? Information in the above referenced audit report confirms that the southwest US is the next region to start the build out. I am currently in the Phoenix area (more on that in another blog entry) and have noted there is a P-25 control channel on 165.6375 MHz. It is part of the Phoenix area P-25 trunked system that allows federal VHF users to tie directly in to the 800 MHz system without patches.
